This article shows the results of applying social network analysis techniques to explore the antecedents in the formation of collaborative learning networks in Chile. Immersed in learning analytics, the paper indicates a set of individual variables of students that explain the relationship structure between them for the purpose of collaborating in the study. In particular, the study used a Multiple Regression Quadratic Assignment Procedure to analyze a network of students belonging to a Chilean university. The results support the existence of three antecedents in the formation of a network to collaborate in the learning: homophily, closeness in the academic performance and looseness in the happiness level.
